Other then being a little rich anyone see anything on this small log I should address?
thx

 

Your injector duty cycle is too high from 5500 rpm and up. I would not go not go higher than 85%IDC. You need to lean it out first to the AFR you want to run then tune the timing. For a IX that looks like a lot of timing up top.

 

If you don't have an upgraded fuel pump, it will let you pull a lot of fuel and lower your IDCs. 10's are definitely too rich though... stay out of 10's completely.

Try a few clicks more timing at peak torque... you should be able to run 4-5 without an issue.

 

On the tuning primer i was reading "Setting your AFR depends to a large extent on the boost and timing that your car is running" so timing comes first right?


I have a Walbro 255, also I am fighting a MAFT Gen 2 so it a hand and hand type thing on the AFR's

thx for the input guys

 

Another log for the fire:

I was able to bring the timing back down in the high range and get the AFR's in the low to mid 11's now, but I am getting some knock during shifting.

log2 is a pull from 3rd

log3 is a pull from 3rd with shifts to 4th and 5th.

Any ideas?
Thx
